Critical Issue
Description
If you click Import PLL Frequency, the ALTLVDS_TX parameter editor correctly starts, but you can incorrectly edit all parameters not just the Frequency /PLL Settings page parameters.
This issue affects all configurations.
There is no design impact.
Resolution
To work around this issue, when the ALTLVDS_TX parameter editor starts on the General parameters page, follow these steps:
- Click Next to go to the Frequency/PLL Settings page.
- Select desired input clock rate.
- Click Finish twice to skip the remaining pages and close the ALTLVDS_TX parameter editor.
This issue will be fixed in a future version of the POS-PHY Level 4 MegaCore function.
